To all whom it may concern,"

lle it lrnown that l, Waarna G. Banana, a citizen ot the lUnited States, residing at Meriden, county ol New lilaven, @tate ot Connecticut, have invented a certain new and useful improvement in lacuumlnsulated Vessels, ot which the tollowing is a lull, clear, and exact description.

h/ly invention relates to improvements in vacuum vessels and has lor its ohjgect to prolvide a vacuum vessel having a' casing ot a character which holds the vessel snugly in position. provide a vessel having an inexpensive cas ing which presents a nnished appearance vand canhe easily manuiactured.

llhe following' is a description oil an emloodiment ot, my invention, reterence heing had to the accompanying drawings, in which:`

lligure l is a side elevation ot an emhodinient ol my invention, showing the casing ot the vessel, the same consisting oi a hody portion and a cap; v

llig. is a partial vertical section ol the sae, the vacuum insulated container heing1 shown in lull lines within the casing, and the latter heing in section;

llig. 3 shows a detail ot the top part oi the hody portion oi the casing; 4

llig., 4l' shows a plan view ol the saine, and

same.

Referring more particularly to the draw,- ings,'the loody portion ol the casing consists oi a cylindrical holder 1, having at its upper end a head or Harige 2 and a screw-threaded ring 3, whose lower portion 4l is spun or pressedaround the tlange 2, as shown more clearly in l? ig. 3. rlhe ring Bis provided at its upper edge with downwardly turn lli tongues 5, which are integral with an inwardly projecting dange 5 and present lateral hearing surlaoes 'lor the vacuum insulated container 6. These tongues 5' slant-inwardly slightly so that when the container 'is placed in position they can yield slightly lt further has tor its ohjiect to against shoc llig.. 5 shows a perspective view oil thel l and thus hold the upperl end ot the container snugly. 'l is a cap,l which is screw-threaded at its lower end so as to engage the screwthreads upon the portion 3, and is adapted to he used as a -cup when removed trom the hody portion. 'lhe loody portion containsv centering springs 8, which extend upwardly adyacent to the inner wall ot thecasing and engage the outer wall ot the" lower portion ot the vacuum insulated vessel at tour points spaced apart hy ninety (90) degrees. 'llhese sprlngs have inwardlyand upwardly ertendingportions 8 to which is secured a holder 9, containing a cork ring l0 on which the hottom -ot lthe vacuum insulated container ti seats, as shown in llig. 2.

The screw-threaded portion 3 ol the casing is tormed separately trom the lower porat'v the dange or head Y2 so as to he held nrmly in position. v

'lhe casing thus termed holds the vessel hrrnly and iet protects it to some extent s, and presents a idnished appearance, the dange 5 coverin the space hetween the vessel andV the vertical wall ol the casing. i

its willhe'evident to those skilled in the art, my invention permits ol various modications, without departing trom the spirit thereof or the scope ot the appended claims.

-at 'l claim is: l n l. A vacuum insulated vessel comprising a container, a vertical-wall casing there gtor composed ot a hottom portion, and a 'lllv4 allv separately tormed top ring secured thereto,

cured thereto, said ring having at its upper end an internal harige and downward prottl `rately formed screw-threaded top ring sejecting means engaging the outer surface 'of the vessel and spacing said 'vessel away from the vertical wall of said casing.

3. A vacuum insulated vessel comprising 6 a container, a vertical-walled casing thereforcomposed of a bottom' portion, and a separately formed screw-threaded top ring secured thereto, said ring having at its upper end an internal flange and a plurality of l downwardly and inwardly projecting pro- 10 jections engaging the outer surface of the vessel and-spacing said vessel` away from the vertical wall of said casing.
